v Claims.

The invention relates to a pencil sharpener and more particularly to draftsmans pencil pointer.

The primary object of the invention is the provision of a pointer of this character, wherein a sanded paper is held and backed in vcircular formso that the point of a lead pencil canflbe applied thereto and through clockwise and counterclockwise motion imparted to the pencil the lead will become pointed and conically tapered with dispatch as is required by a draftsman, and in this manner eliminates the use of a file, emery bar or the like, which usually requires a considerable amount of time and is a dirty procedure.

Another object of the invention is the provision of a pointer of this character, wherein the construction thereof is novel in its entirety, it being readily portable, easily handled and is a trap for the lead waste from a pencil and thereby resultant in cleanliness during the execution of drafting work.

A further object of the invention is the provision of a pointer of this character, wherein a wide area for sharpening purposes is available and pencils of different sizes of lead in cross section can be quickly and readily pointed without excessive exertion on the part of user of the pointer.

A still further object of the invention is the provision of a pointer of this character, which is simple in construction, thoroughly reliable and efficient in operation, easily handled, enables the replacement of sanded paper with dispatch, strong, durable and inexpensive to manufacture.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a plan view of the pointer constructed in accordance with the invention.

Figure 2 is a rear view thereof.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is a fragmentary plan view of the sanded paper blank used in the pointer.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally the pointer constructed in accordance with the invention, and comprises a cup-shaped body Ill, preferably made from metal,

although it may "be made from any other sheet material, and a bottom section II, the latter being'formed with'a rim I2, while the body I!) is provided with a reduced inner neck portion I13 The m nd eck p t o a par bly joi ed with ea h oth by c mp n on threads I4. [The body I0 next to the neck portion I3 can be gripped and securely held between and by the shoulder and flange to have the paper I8 backed by the side wall of the body II] with the sanded side of the paper I8 exposed interiorly of the body.

It will be noted that the side wall of the body I0 gradually decreases in circumference toward the shoulder I5 and to have the paper l8 conform to the angular disposition of the shoulder and flange the edge I! is V-notched at I9 while the meeting ends of the paper I8 are overlapped at 20 and glued orotherwise tacked together at this point for permanent formation and snug fitting of the paper I8 in the body as has been indicated.

Through the arrangement of eyes 2! on the bottom section II there is permanently associated with the latter a handle 22, which projects laterally from said section I I for the hand gripping thereof. This handle 22 is convenient for the screwing and unscrewing of the body I0 and bottom section II for the mounting and dismounting of the sanded paper I8 as the occasion may require. The screwing operation of the body Ill and bottom section II relative to each other is for the purpose of mounting and unmounting of the paper I8, the body I8 being the carrier therefor.

The method of pointing a pencil by the device is to first grip the handle 22 with the left hand of a user and insert the pencil A into the body I0 until all protruding lead of the pencil comes in contact with the sanded paper I8 and the axis of the pencil must be parallel with the center line of the pointer B then by a slight outward radial pressure and clockwise motion on the pencil A will produce a conical point on the lead as is desired by a draftsman.

It will be noted that the overlap 20 of the paper is free of sand for the accommodation of glue or other tacking medium, and that the notched edge I! of the paper I8 is guided in.

place by the shoulder 15 on the fitting of the paper l8 within the body I.

What'is claimed is:

1. A device of the kind described, a body of cylindrical contour, a bottom adjustably connected with the body, a shoulder on the body, a clamping flange on the bottom coacting with the shoulder, and a sanded paper sleeve fitting within the body and secured between the shoulder and flange for exposing the sanded area of the paper interiorly of said body.

7 2. .A device of the kind described, a body of cylindrical contour, a bottom adjustably connected with the body, a shoulder on the body, a cl'amping flange on the bottom coacting with the shoulder, a sanded paper sleeve fitting within the body and secured between the shoulder and flange for exposing the sanded areas of the paper interiorly of said body, and threaded con-' nections between the body and bottom.

s. A device of the kind described, a bodybf cylindrical contour, a bottom adjustably connected with the body, a shoulder on the body, a

clamping flange" on the bottom coacting with the shoulder, a sanded paper sleeve fitting within the body and secured'between the shoulder and flange for exposing the sanded area of the paper interiorly of said body, threaded connections between the body and bottom, and a handle car- V ried by the bottom.

4. A device of the kind described, a body of cylindrical contour, a bottom adjustably connected with the body, a shoulder on the body, a clamping flange on the bottom coacting with the shoulder, a sanded paper sleeve fitting within the body and secured between the shoulder and flange for exposing the sanded area of the paper interiorly of said body, threaded connections between the body and bottom, and a handle carried by the bottom, the body and paper being similarly shaped and of inverted conical formation.

- 5. A pencil pointer formed with three parts, and comprising a cylindrical body having a re- .duced screwthreaded base, the portion of the I body connecting the same to the base being angular and providing a shoulder, a sorewthreaded bottom part engaging the screwthreaded base of the body and having an angularly flared flange engaging the shoulder on the body, to provide a clamping means, a sanded paper sleeve fitted within the body and secured between the shoulder and flange to expose the sanded area of the paper interiorly of said body, the edge of the sleeve being V-notched to fit the paper to the body, and a handle carried by the body.
